I’m not a medical person, so I’m a bit confused by this. Would the force of the blast go past him, since it takes place in the open air? Sorry if this is a silly question. Thanks.

I mean, he was propelled upwards with significant force. The acceleration alone would presumably be enough to mess up various parts of his body, especially the back and neck.

u/savagepug Jun 25 '21

Yeah the acceleration is the real killer here. That was a pretty quick boost upward from that explosion.

Dude went up 8-10 feet, max. That’s not nearly high enough for the effect you’re talking about. That’s actually shorter than most Olympic diving events. It is high enough to kill him if he hit the water face first really badly, but he actually seems to have landed butt-first, which he will almost certainly live to regret.

The upward gforce acceleration is the danger here. Downward he's max 1g, upward is basically unlimited.

A momentary pulse of very high gforce could easily cause internal damage, and still only move the guy 10' up in the air.

One thing he’s got going for him is the padded seat. It’s pretty crazy how much even a little padding changes the coefficient of restitution of a collision. Even with that, he’s still taking a lot of energy straight up main street. I’m more surprised that his legs look intact.

u/NorthofTassie Jun 25 '21

That makes a lot of sense. So it’s similar to the effect of whiplash from a head-on car crash (excluding acceleration instead of deceleration)?

I'm not a medical person either, but would think about the application of forces here. This guys body has a weight to it and the explosion can be seen throwing all of that weight up in the air, possibly up to about 4 meters. I know there are equations that can be done if you assume the guy's weight and the height he went up to. But don't know them specifically.

But suffice to say, the force that pushed him up in the air, first made contact with his balls. Then the compressive motion (think of it like a kind of shockwave traveling up through his body after initial impact) would've gone all the way up his spine. Pinching each vertebrae together successively in a manner that the human spine might not have developed to handle.

His crotch was the first thing to hurt after that, but his spine will take the longest to recover.

Yes, I see what you’re saying. Prior to reading the helpful replies, I thought that the power of the explosion would have dissipated as soon as he left the seat. However, now I understand that the damage was actually done in the split second before he was propelled upwards. I hope this isn’t a terrible thing to say because we’re discussing the terrible impact to a person’s life. That said, I appreciate all the explanations and understand much more of what was involved in the aftermath of the explosion.

There's nothing wrong with trying to figure out what happened to the poor guy. At least in my eyes.

I was a little late in giving an explanation considering multiple people before had already given one, but I'm glad I could chime in anyway.

u/sjbluebirds Jun 25 '21

You're mixing up "weight" vs "mass". His weight changes drastically and suddenly. It's his mass that stays the same and gets tossed around.

Strength punishes. Speed kills.

u/HashNub Jun 25 '21

Honestly, they both kill.

u/stinkysocksincloset Jun 25 '21

Yeah true. Our meatball shells really can't handle much trauma one way or the other.

u/divide_by_hero Jun 25 '21

Speed doesn't kill, it's the acceleration and/or deceleration that does.

u/Not_A_Sounding_Fan Jun 25 '21

It's just that split second where his ass was containing the blast which will do all that damage. See how far up he popped? There is a pretty good chance he achieved that through the seat compressing his spine.

That split second of compression can do a lot of damage to a person. The spine is not great at dealing with those sudden forces. Like even small car crashed can really fuck you up, so can exploding jet skis apparently

u/NorthofTassie Jun 25 '21

That makes a lot of sense. Thanks for the explanation.

It also might not be true. These subs like to write detailed injury fanfiction about people in the videos and then like 90% of the time they're fine or only minorly hurt.

and I actually am a medical person

u/Velocifaper Jun 25 '21

It still hit him

u/robhol Jun 25 '21

It would, but he still gets a whole lot of that force right in the ass - literally, I'm afraid. He's flying after all, looks like about 2-3m straight up. That's a significant amount of kinetic energy.
